This awesome AT&T Trimline Phone is Burnt Orange, has a Rotary Dial & is ready to hang onto a wall outfitted with a wall plate & jack.
The Trimline phone was introduced in 1965 with rotary dials. In 1966 touchtone capabilities were also offered.
According to the Trimline Wikipedia page:
In 1983 ‘AT&T begins selling phones, including the Trimline, to the public (as opposed to their previous leasing only policy).’
In 1984 ‘AT&T is divested of its regional operating companies and is prohibited from using the Bell name or logo, so the American Bell brand is dropped and replaced with simply AT&T.’
In 1985 ‘the rotary Trimline is discontinued…’
Because this particular phone has the AT&T logo that they began using in 1983 & has a rotary dial, I believe that even though it may have been produced in the 1960s, 1970s or 1980s, it was likely purchased between 1983 & 1985.
